The second problem is esily solved by reading the readme and understanding how the mod works.
To calrify if you did read it and you didn't get how the combat works in the mod:

Almost all weapons kill in 1 shot now, BUT there's a dodge pool (look at the upper left number) which lets you avoid damage, the only way to really hit somebody is making them spend all of their dodge pool after you have done so a hit will kill them (not that if they have some dodge points left but not enought to fully dodge the hit they will take partial damage).
